IVU Class Reference

#include <MIDI_Inputs/InterfaceMIDIInputElements.hpp>

Detailed Description

An abstract interface for VU meters.

To allow for both floating point values and integers, all values are integers under the hood.

Using floats instead integers would be a strange choice as LED bar VU meters have discrete levels.
Continuous "analog" VU meters can use or override the getFloatValue() method.
